I have a scenario where 7604 is connected (upstream) to 7200 (downstream) over 2 Ethernet links. OSPF is configured over 2 ethernet links. Ethernet links are connected to the switch and terminated as sub-interfaces in single physical interface of 7604 and 7200.
Suppose say both the ethernet links are taken for 10 Mb each and the peak traffic to the downstream location is 16 Mb.
Now when the traffic flows from upstream to downstream it is not getting load shared evenly over 2 ethernet links. One ethernet link carries 10 Mb and other one carries 6 Mb. Thus traffic flowing on first ethernet faces heavy packet drops.
But OSPF cost for 2 ethernet links are same and routing entry to the downstream's loopback shows 2 ethernet links in upstream (traffic always flow to the downstreams loopback).
Since 7604 is not supporting per packet load sharing configuration in interface, i m not able to configure it.
Is there any way that I can configure to have a distributed load sharing over 2 ethernet links.
